Presently, a Detailed Asset List Report generated by my Pat Guard, includes fails- for the failed item it shows last test date ,next test date, last visual, next visual test date. Whereas, items that pass only have the first three.

This is confusing the hell out of some of my customers, can I tweak it to show last test, last visual for fails?

Southseas, not sure if I understand your question.If you don't want dates in the next test & next visual columns for failed items you need to open the item's 'Asset Details' window and change both Test Periods to 'No Re-Test' before running the Detailed Asset List Report. Hope this helps
